Abstract: In 1995, or over the past few years, Quantum Cascade Laser (QCL) was introduced to the world. It is a device known to produce useful terahertz radiation. [1] However, due to fabrication defects, they are highly sensitive typically. Further enhancement of this limitation has been solved by using topological robustness. There are many articles about the usage of properties, some of the experiments and testing on QCLs for the past few years, such as high-power terahertz QCL, relative intensity noise of a mid-infrared QCL and strong optical feedback stabilized QCL. [2] Many people continue to look for new experiments that can help to explore more solutions. This thesis gives an idea of finding available approaches to achieving broadly tunable single-mode quantum cascade laser. Therefore, the main objective is to introduce the characterization of QCL, as well as its solution to achieve the goals and make them approachable. From there, we can do more experiments, and testing and obtain the results to see which are the possible ways.
